If a rocket can be reused once per day (land, refuel, launch it in the next 24h) then there's no need for it being hypergolic.

1. Where is such rocket?

2. A rocket on duty can deliver the rescue craft in an hour.

Orbital inclination of the craft in distress is going to make things difficult, though. Its not enough to have enough payload capacity to LEO. You have to have enough dV to match orbits as well. Or wait until the orbit passes over the launch site.

As long as you can wait half a day, inclination is not a problem, as long as you're launching from the same or lower latitude as the craft to be rescued. Given that, Kourou could be a good site for an "Orbit Guard" base. Just build a few silos (for easy weather protection and access) holding solid or hypergolic LVs with rescue craft mated to them, ready to launch on command.

It's no problem to have two silos with rescue ships, but a 20 t payload can deliver a multiseat rescue capsule to any orbit.

Assuming the launch site is right on the equator.

Assuming the capsule is 10 t heavy, so you get another 10 t to neutralize the Earth rotation speed..

it's not here yet, but it is coming FAST. it is being built by the same guy that sent his car UP.

Starlink core landing failure:

Hans said that the core decided to spare the ship by landing away from it due to detecting winds that were not what was predicted.

Hans reiterating for ascent this time (but it was what he said about landing as well) that it's not just wind speed, but wind shear, and he said most importantly how predictable the shear is. They can fly the rocket through shears (both ways), but they need to know ahead of time what they are at each place. Unpredictable is what lost that last booster on landing.

As failures go, that is a good one.

So in other words, it ditched. Better to just lose the booster than lose the booster and damage the ship. I see that Arnie approves
